Rose plant-ruimior

ABSTRACT

A miniature rose variety having a dwarf, compact plant, producing, when small, buds and blooms of Poppy Red; able to be propagated easily from cuttings and suitable for use as flowering pot plants.

This present invention relates to a new and distinct variety of rose plant of the miniature class which was originated by crossing the variety Rufin with an unnamed variety.

The primary objective of this breeding was to produce a new rose variety of small size suitable for production of flowering pot plants as well as useful for garden decoration. This objective was substantially achieved along with other desirable improvements as evidenced by the following unique combination of characteristics which are outstanding in the new variety and which distinguish it from its parents as well as from all other varieties of which I am aware:

1. Readily propagated and grown on its own roots by cuttings;

2. Initial blooms when plants are approximately 6" high;

3. Blooms carried in clusters as well as one per stem;

4. Bud and bloom color near Poppy Red (Wilson); and

5. Heavy petal substance causing flower to retain form until dehiscence.

Asexual reproduction of this new variety by cuttings, as performed at Irvine, Calif., and Hazerswoude, Holland, shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar with color in terminology in accordance with the Wilson's Horticultural Colour Chart except where ordinary dictionary significance of color is indicated:
